Ashley and I were on a ski vacation, and we couldn't wait to hit the slopes -- until we heard the scary legend of Ski Mountain. According to the story, a monster snatched a boy right off the ski slopes! The boy was never seen again.

But it was just a story. Or that's what we thought.

Until our ski lift stopped mysterious in midair...

And the tree outside our cabin was ripped apart...

And we found giant footprints in the snow.

We were on the case. Was there really a Ski Mountain monster? We were about to find out -- one way or another!
